Simulated impact of paleoclimate change on Fremont Native American maize farming in Utah, 850–1449 CE, using crop and climate models

Our paper in Quaternary International just went online today. The pithy takeaway: Ancient dryland farmers in Utah adapted to warming and drying during the MCA but were unable to adapt to increased variability at the MCA-LIA transition, and abandoned the area for maize farming. Because increased variability is one of the near certainties for temperate semi-aridContinue reading “Simulated impact of paleoclimate change on Fremont Native American maize farming in Utah, 850–1449 CE, using crop and climate models”

AGU Paleoclimatology session

They never know quite where to put me at AGU. But I was very pleased to see that this year others are getting into the same things I have been: (1) strange behavior of the Medieval Climate Anomaly (MCA) in the Southwest USA; and (2) computer models! Omid Mazdiyasni (UC Irvine & YSSP2016) came byContinue reading “AGU Paleoclimatology session”
